Yes, absolutely.  RTF is only modestly more accessible than PDF (or Word or
WordPerfect for that matter).  Sure, its a shared non-proprietary format,
but there are no public specifications for "validity", let alone
"accessible".  Besides, all of those formats are presentation oriented -- as
opposed to HTML which was MEANT to share information (and is being ABUSED
when used for GUI formatting effects).
